ELECTRIC GRIPPER Product Lineup Electric grippers for the RCX240 controller Easy to operate since YAMAHA robot language gives unified control Gripping power control Settable in 1% units from 30 to 100%. Measures a workpiece by position sensing. Speed control Multi-point Control Settable as needed in 1% units from 20 to 100% for speed and 1 to 100% for acceleration. A maximum of 10,000 positioning points can be set. Workpiece check function Workpiece function Utilizes the HOLD output signal to check if the gripper fails to grip a workpiece or drops it, without using a sensor. Plenty of lightweight, compact model variations Single cam type Lightweight, compact, high-speed Single cam structure Unique cam structure is simple and compact. The fingers work due to external force since no self-locking is used. Double cam type High gripping force Double cam structure Unique double cam structure with gear. Simple design gives high gripping power yet body is compact. YRG-2005W Screw type Strait style High precision, long stroke Ball screw structure Belt-driven ground ball screw delivers a long stroke with high efficiency and high precision. YRG-2020FT/YRG-2840FT Three fingers type P.461 Compact, high rigidity, long stroke Compact ball guide structure Use of special cams provides light weight and compactness. Ideal for grasping and moving a round workpiece made of glass or similar material. YRG-2004T

Electric gripper for high-precision gripping power, positioning, and speed control Combination with a vision system supports wide ranging applications YRG delivers gripping power control, speed and acceleration control, multi-point positioning, and measuring of workpieces, which have been difficult for air-driven devices. The YRG proves a flexible fit for a wide range of applications. Even sophisticated systems can be easily configured by using the YRG series gripper in combination with a controllerintegrated robot vision “iVY system". ■■Connection example Robot vision system: iVY System Controllable...

APPLICATION TRANSERVO Screw type strait style YRG-2020FS/2840FS Gripping power vs. gripping power setting (%) 200 Linear motor single-axis robots • Graph shows a general guide to gripping power versus gripping power setting (%). Variations will appear in the actual gripping power. SCARA robots Note 1. Design the weight of a workpiece to be held so that it is approximately 1/10 to 1/20 of the holding power. (Consider further allowance when moving and swinging the gripper that keeps holding a workpiece.) Allowable load and load moment Pick & place robots Allowable load Allowable pitching moment...
